NAME
  xzoom - magnify part of X display, with real-time updates

SYNOPSIS
  xzoom

  xzoom [args]

  xzoom [-x ] [-y ] [-mag magnification]
        [-geometry 'width size' x 'height size']

DESCRIPTION
  Xzoom displays in its window a magnified area of the X11 display. The user
  can interactively change the zoomed area, the window size, magnification
  (optionally different magnification for X and Y axes) or rotate or mirror
  the image.

  Use commands to change rotation, zoom or mirror the image.

OPTIONS
  -d <displayname>, -display <displayname>  
         The name of the display to use.

  -mag <magnification [ magnification ]>  What magnification to use. If two
  number arguments are supplied the first is used for X magnications and the
  second is used for Y magnification. Magnification should be greater than 0.

  -geometry <geometry>  Size and position xzoom's window.

  -source <geometry>  Size and position the initial source area which is
  magnified. The dimensions of this area are multiplied by the magnification
  to get the size of xzoom's window. If these dimensions are given separately
  (by use of -geometry) then an error is reported.

  -x  Mirror horizontally.

  -y  Mirror vertically.

  -xy  Exchange X and Y axes before any magnification is performed.

COMMANDS
  +  Increase magnification value by 1.

  -  Decrease magnification value by 1.

  x  Mirror the display image horizontally.

  y  Mirror the display image vertically.

  z  Rotate 90 degrees counter-clockwise.

  w  Next '+' or '-' only change width scaling.

  h  Next '+' or '-' only change height scaling.

  d  Sets the delay between frame updates. Built-in delays are 200, 100, 50,
  10 and 0 ms.

  q  Quit.

  Arrow keys  Scroll the zoomed area 1 pixel in the direction of the arrow.
              if the control key is pressed the zoomed area will scroll 10
              pixels.

  Mouse buttons  To set the location of the magnified area, click the left mouse
                 button inside xzoom's window and then move it (keep the button
                 pressed) to the place which you want to see magnified.

  Xzoom allow you to resize it's window at any time.

  When xzoom is iconified it simply waits to get deiconified.
